I think our new sofa bed will be perfect both as a sofa and occasional bed. Comes in removable sections so relatively easy to get up the stairs once unpacked (although the bed bit does like to try and spring up). My wife and I put it together in about 20mins, instructions were good. As with many new sofas it is pretty solid to sit on, but will give good support as a mattress and there’s plenty room for cushions. Good storage compartment underneath too.
